It was great and arrived home a little sooner than expected which is nice.

I fly out every other weekend and this is the 4th time my flight has been delayed at Southwest. I will be flying out twice a month on average for the next 6-7 months. If this is your average ‘on time’ I’ll probably be flying another airline.

WiFi was inoperable - second in four recent Southwest flights where that was true. I need WiFi for work and if Southwest cannot provide, I’ll stop using it

It’s too cold like fridge and they don’t offer a blanket with expensive price

Boarding now takes twice as long since going with assigned seats.

Smooth flights, connection, and friendly crew in the air and at the gate.

Flight was delayed again. I fly out every other weekend and lately the flight is delayed 3 out of five times 🤷🏻‍♀️

A List preferred boarding was nice Asked for a mask and cheerfully received Denver bag check-in is tricky. Not near other checking desk. Have to navigate to east security and up to level six for bag checkin. TSA busy and 20 minutes process thru pre lines Denver train to gates quick but one more thing to plan time for and long concourse walk to gate

Not exactly Southwest’s problem, but the new Burbank airport is not great. No restaurants open and tons of work still to be completed. Can’t believe they opened the airport in that condition.

Boarded the plane in Portland and sat on the tarmac for four hours before being given clearance to take off. Apparently a "scratch" was detected on the preflight inspection. This delay resulted in me missing my connection in Baltimore. I therefore had to stay overnight and then catch an early flight this morning, which resulted in my missing a mandatory class. I would like a refund / voucher to cover the cost of the missed flight. And additional voucher for the time spent on the plane in Portland would also be appreciated.

attendents were rude and the boarding was disjointed and poor

Delta keep on impressing me. Right now Delta airline is the best of them all

Very good- all went as planned. Flight was on time. Seating was a little sub , as always. Snacks and entertainment were basic. We arrived on time- no problems.

Everything was great, from the flight and crew to the seating and snacks.

Rude staff from baggage check to gate crew. Poor instructions. Inconsistent application of baggage rules.

There was an incredibly surly flight attendant that ruined the experience

Easiest airport experience ever in my life at MSP with Delta check-in and flight attendant gave us a bottle of champagne in celebration of our 10-year wedding anniversary, so overall amazing!

Great. Seamless. Check in agent at kiosk international was amazing and extremely helpful.

Delta did an awful job w logistics at DTW. Missed connection. We were there an hour early. SUCKED

Delta planes have the WORST seat comfort of any plane in history. It's the opposite of ergonomic, in every sense. They also recline minimally, are covered in a vinyl and have no feet rests. Then the disembarking process is chaotic and time consuming (because of the way they load the plane and deal with luggage). Overall, somewhat frustrating but we arrived safely :)

Miss My connection I had to take a flight from Indianapolis to Denver , then to san fransisco , sleep in sans fransisco en the flight to Los Cabos the next morning

Not so good. Crew was not as attentive as they should have been especially if flying business class. Only offered dinner 2 hours after takeoff. My flight attendant seemed overwhelmed. Pushed my help button but no one came. I explained everything on my previous review.

My flight from Boston to SFO was fine. Crew was friendly and helpful. Food was mediocre. Fright from SFO to MNL was not as good. My flight attendant was friendly but didn’t seem to have a lot of experience. She seemed overwhelmed. Also, this was the only red eye business class flight I’ve flown which only served dinner 2 hours after takeoff in a 13 hr flight. When I woke up 1 hr before landing, everyone was eating so I assumed bkft was being served. I pushed my button for help and no one came so I approached my flight attendant and she said they don’t serve bkft but she gave me choices for lunch or dinner. I routinely fly business class but I was disappointed with the lack of service and attention I was given on this flight. Also, most airlines will offer a snack or coffee before bkft is served but this was not offered during this flight. Overall, it was disappointing.

The first leg of my trip the Republic Airlines aircraft was late due to a maintenance problem. Then I called United to reroute. Their reroute airline lost my bag but found it and returned it two days later. Hopefully my return trip home is better.

There was not even a single time where united airlines from lga has made to the gate straight , 1 hr if delay today

Both my flight where delayed Had 25min to make it to my transfer flight

My experience on this United Airlines flight was highly uncomfortable, primarily due to two issues: Cabin Temperature: The temperature on the Boeing 737 MAX 8 was unacceptably high, feeling consistently around 80 degrees throughout the flight. This made sleeping impossible and significantly detracted from the experience. Seating Arrangement: Being stuck in a middle seat for a six-and-a-half-hour overnight flight compounded the discomfort. Moving forward, I will always purchase a seat assignment to avoid this situation.

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

They changed my flight 5 hours before it took off and changed my connecting airport messing up my entire 1st day in Japan.

I had very little time to change planes originally in Denver after my flight from Omaha. I had an hour and a half layover in Denver originally and my flight leaving Omaha was delayed an hour because they had to change a tire, which I can understand. When I reached Denver my other flight was late, fortunately, but I still had only 10 minutes to run about a mile through the airport to get to my flight. Again, fortunately, I am a healthy 71-year-old and was able to accomplish this feat. However, the stress was more than necessary to bear.

I am always very pleased with the service u receive from JetBlue employees

Your Jet Blue representative at the check in desk in Boston on Sunday morning, October 13, was unkind and unhelpful. For that reason alone I will avoid JetBlue airlines in the future. No food or beverage on the flight due to turbulence (not your fault). However I paid extra to sit in the upgraded section in the front and did not benefit from most amenities.

we used to fly with a different airline but it shut down. We had to find an alternative airline that we like in order to make domestic trips and this fits the bill. Not only is it a similar price but the customer service and the experience overall is much much better. We will be using JetBlue again.

Uncomfortable seat. No help for my disability. Staff refused to help me put my carry-on in the overhead bin. So I had to check the bag.

Terrible. Quality has gone down significantly. Plane was delayed. No instructions from the staff. Will try to avoid in the future!

What's not to like? Value?definitely. Every JetBlue member was extremely friendly on this flight. Very very nice new-ish aircraft,plenty of room. GOOD coffee. Entertainment,I didn't need it,but I think its available. What to do better? Well,there's nothing we can do about the other people, unbelievable how some folks are operating. Just don't allow people to lug all their stuff onto the aircraft. 1 bag. That's it. Be easier for you too. I personally would enjoy more options in schedule. One flight in and out a day is warranted given the local,I understand, but the times are inconvenient. Again, I completely understand why it is that way,It would however be great to have different options.

see my previous response about being kicked off the flight and having to fly the next day, ruining a planned vacation tour.

The flight departed more than 1 hour late. Leg room is bigger than most airlines

terrible. Because I felt very unwell during the flight. How do they leave a woman alone in the middle of 2 men? an obese man who was falling on top of me.

I booked this flight using JetBlue points and I was just so happy. The plane was so clean, I had every need met. Thank you!!

Good flight, excellent personnel; poor comfort, small seats, big cost.

No flight delays. No need to rebook to make connections. Enjoyed second leg of flight on Iberia.

Very Good in general. Serving attitude are very good. Just a suggestion: There 2 things can be improved: 1. The flight attendants can lower the voices when they talked in the serving station. Sometimes they talked loud and we could hear clearly what they said about the passengers. 2. Please don’t throw the utensils and plates it’s too loud and noisy. They broke the glasses and plates sometimes at the business class. These all could be done in a gentle way. Just some small observations. Thanks.

Flight was delayed a couple of times. Which is annoying, but manageable.

Both directions of our trip were befuddled by massive delays, one of which led to our connecting flight being grounded mid air due to storms that we’d have missed if we were on time. The other our originating flight was delayed repeatedly until it arrived at our connecting airport later than our final leg was even supposed to have arrived. American cannot seem to manage rebooking s for a family party… both directions we had to come up with a plan to get to Boston stay overnight only one night each direction was covered by the airline -and take a bus to or from our destination. Missed an entire leg of our trip, hotel cancellation fees, expensive stay in Boston and bus ticket expenses are unlikely to be comped and the meal vouchers are worthless.

My flight was 4 hours delayed on departure at 6a causing me to miss my connection at DCA. I had to scramble to find a seat home on a later flight and instead of an exit seat, I was in row 30 on a flight getting me home 5 hours later than planned. The AA team on the ground did a fine job. AA continues to run the airline like the passengers are cargo.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

A much better flight than our previous. The flight attendant took care of us and regularly checked in to see if we needed anything. Brought us drinks prior to the departure and then a couple more times. Totally makes the difference in how you travel when the crew is checking on their passengers. Great job on this leg of our trip.

Flight was delayed after boarding and no idea when it would take off. Crew in Portland did arrange for transport to Boston for a different set of flights to my destination.

Seats are so close together. Middle seats should be discounted.
